C. to describe the stone and its engraving
The statue that P.B. Shelley talks about in his poem "Ozymandias" is of a once powerful king. The poet has used source material to describe the present state of the stone statue and the engraving on it.
The following excerpts from the poem give the answer to the question :
1. "Who said: “Two vast and trunkless legs of stone
Stand in the desert . . . Near them, on the sand,
Half sunk, a shattered visage lies, whose frown,
And wrinkled lip, and sneer of cold command,"
2. "And on the pedestal these words appear:
‘My name is Ozymandias, king of kings:
Look on my works, ye Mighty, and despair!'"
